Tonight on GeekNights, we consider the issues around Apple's stand against the FBI, the dangers of crypto backdoors, etc... In the news, the machine learning revolution continues by mining social media to source food poisoning outbreaks more effectively than traditional inspections. This breakthrough joins the final end of human input into the game of Go, one of many advances in what appears to be an accelerating field. Google technically complies (the best kind of compliance) with Europe's ridiculous data censorship rules.

All they are doing is the obvious thing that a big company would do in the same situation but are using it for marketing and advertising because the FBI were silly enough to think it would be cool to go public with the request. Your case didn't fail, your fans failed lol. Just buy some Noctua's they are super quiet and have like a 6 year warrany, they may seem expensive but I've yet to replace a case or heatsink fan.
Also clean out your case maybe 2 times a year f you have a high flow case without any dust filters . The nehalem's were literally all the same silicon, especially the first few batches, with different lock downs. I overclocked my 930 (released when i7-920's ran out of stock) to 4.2ghz (faster than the 980 clock for 1/3 of the cost).
The 920 was the best of that generation if you knew how to do the most basic hardware overclock.
I literally only swapped the CPU out a few weeks ago because my CPU became unstable at the overclock and would only reliably work at 3.2 ghz (base clock). My Graphics card and SSD were being choked due to the CPU.
I was still on 6gb of RAM.
Upgrading RAM to DDR4 (16gb), a new motherboard and CPU, literally increased all my CPU capped processes by factors of 2 - 3. CPU capped games now run at 600 frames per second as an example.
I think the primary bottlenecks have been CPU/ GPU. Mostly the CPU. For GPU, I need more CUDA cores and graphical RAM.
For the CPU, faster cores only help so much. Having more of them is the way to go.
If you're infinitely wealthy you could just build a giant render farm on a rack and not need to upgrade ever.
Eventually, I plan to build a dual CPU workstation for all things work related. For the gaming rig, my 2011 just needs a new GPU. Still rocking a punkass 460. I've already seen what a 970 can do and I'm salivating.
So I didn't buy the top of the top: I bought the top of the price/performance curve just ahead of massively diminishing returns per dollar spent. ;^)
I'm not one for conspiracy theories, but I think it's reasonably likely that the FBI put the county officials up to reset the Apple ID password on purpose to force this particular case simply because it's the best public-facing argument the FBI has seen until now. Apple is preventing the FBI from cracking a dead terrorist's iPhone? Only privacy advocates, crypto enthusiasts, or techies could possibly give a shit. It just looks bad for Apple, which is why the FBI made this a public request.
One relatively simple update Apple needs to do is have the user unlock the iOS when doing an upgrade. I guarantee that will happen ASAP, possibly with iOS 9.3. I'd be doubly impressed if Apple released an iOS 7 update that included this feature—I don't think they've ever released an update for an outdated iOS, and it'd be a double fuck-you to the FBI to do so.
The thing is, their suggestion doesn't go far enough. Just copy all the data in all the phone's storage onto a desktop Mac. Then you can try to decrypt those bits directly, or even use the iOS emulator in XCode. You don't need the phone.
This is just human vs human though.
If I had to hazard an uneducated series of guesses:
1. Humans are at the limit of their reasonably coherent heuristics, and have no choice but to fall back on conservative game-delaying draw-favoring strategies.
2. "Going for the draw" is far safer than going for a win, implying that Chess is flawed allowing many infinite loop / neverending game scenarios
3. Humans playing defensively hit on these draw loops despite the limitations of their heuristics primarily because they are so common.
I base this partly on the fact that modern chess requires surprisingly complex "draw" mechanics. See the ridiculous 50 move rule.
So, regarding AI vs human, I suspect that this defensive play style is coming out of human players analyzing modern AI vs AI games and incorporating their degenerate "billion moves forever rick and morty" strategies into their heuristics.
I suspect that the FBI, while dumb, knows they don't need this, and just want to set precedent while they have an emotional backing (San Bernardino shooting, terrorism). If there really was a national security threat, I'd bet money that NSA has Apple's OS signing key, but they do not want to reveal that fact, because they want to keep that shit for mega important operations, whereas the FBI wants iPhone decrypt priveledges for much lower-level stuff.
Newer devices have the Secure Enclave which both enforces the delays for incorrect tries and mixes the passcode with its own embedded key. With that in play, you're in the realm of teasing apart silicon or attempting to sniff out crypto keys and whatnot from emanated EM—which might work, but also sounds much more expensive.
Right, this phone doesn't have an SE and, again, there's currently a loophole that you can force any signed iOS upgrade without first having to unlock the phone. That loophole is an oversight on Apple's part.
Brute forcing a 4 digit unlock is simple. You would just need a script to image a new drive after every 10 tries. Trying to brute force the actual drive would be impossible without a few new algorithms and quantum computers.
